Fuzzy Set Theory—and Its ApplicationsSince its inception, the theory of fuzzy sets has advanced in a variety of ways and in many disciplines. Applications of fuzzy technology can be found in artificial intelligence, computer science, control engineering, decision theory, expert systems, logic, management science, operations research, robotics, and others. Theoretical advances have been made in many directions. The primary goal of Fuzzy Set Theory - and its Applications, Fourth Edition is to provide a textbook for courses in fuzzy set theory, and a book that can be used as an introduction. To balance the character of a textbook with the dynamic nature of this research, many useful references have been added to develop a deeper understanding for the interested reader. Fuzzy Set Theory - and its Applications, Fourth Edition updates the research agenda with chapters on possibility theory, fuzzy logic and approximate reasoning, expert systems, fuzzy control, fuzzy data analysis, decision making and fuzzy set models in operations research. Chapters have been updated and extended exercises are included. |

Real situations are very often not crisp and deterministic, and they cannot be described precisely. 2. The complete description of a real system often would require far more detailed data than a human being could ever recognize ...

An example of the latter is the term “creditworthy customers”: A creditworthy customer can possibly be described completely and crisply if we use a large number of descriptors. These descriptors are more, however, than a human being ...

At appropriate times, however, the additional potential of fuzzy set theory that arises by using other axiomatic frameworks resulting in other operators will be indicated or described. The character of these chapters will obviously have ...

Such a classical set can be described in different ways: one can either enumerate (list) the elements that belong to the set; describe the set analytically, for instance, by stating conditions for membership (A = {x|x < 5}); or define ...
